Question

就跟百度或高德地图一样打开后显示当前位置，我从http://blog.csdn.net/supermapsupport/article/details/50820418#reply
中的评论里下载了demo，里面没有jar包，然后我去官网下载了SuperMap iMobile 8C SP2 for Android_802_8623，拷贝了里面的jar跟so文件，

m_wokspace = new Workspace();
		DatasourceConnectionInfo dsInfo = new DatasourceConnectionInfo();
		dsInfo.setServer(CLOUD_URL);
		dsInfo.setEngineType(EngineType.SuperMapCloud);
		dsInfo.setAlias("SuperMapCloud");
		Datasource ds = m_wokspace.getDatasources().open(dsInfo);

ds获取一直为null,注释掉后运行，就报下面这个错误

我想问下是什么原因，或者有什么可以运行的demo

你好，我之前也问过这个定位问题，官方给了个源码链接，希望对你有用。http://support.supermap.com.cn/product/CodeLibrary.aspx?id=650

我下载的就是这个，里面没有jar 然后就是上面的问题了

你是不是没有在grade是设置

  sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }

我用的Eclipse。。。。

你好，请问问题解决了吗，我运行这个源码时程序会报错闪退，只要注销掉compassview类的实现程序就可以正常运行，这个是什么问题？

请问这个问题解决了吗？请问你是怎样注销掉compassview类？

compassview里图片流解码的那行有问题
